A cargo bed extension assembly includes a tailgate structured to be movable between a raised configuration and a lowered configuration. The tailgate includes a cavity formed therein. An extension mechanism is positioned within in the cavity. The extension mechanism includes an extension member coupled to the tailgate so as to be movable between a stowed configuration and an extended configuration, and so as to enable rotation of the extension member from the extended configuration to a raised configuration. The mechanism also includes a cover portion coupled to the extension member so as to be movable between a stowed configuration and a deployed configuration in which the cover portion covers at least a portion of the bed.

A frame assembly for supporting and mounting a box compartment over and around a flat bed of a flatbed tow truck is described. The frame assembly includes a frame attached to a chassis of a flatbed tow truck. The frame includes at least one left and at least one right side support beams, at least one left and at least one right horizontal connection beams, two or more left side and two or more right side vertical support beams, at least two cross-beams, and at least one vertical connection beam. One or more of the at least two cross-beams is connected to the chassis and is further connected at each of its ends to the left and right side support beams. Each vertical connection beam is connected to either the left or right horizontal connection beam and is oriented generally vertically for attachment of a box compartment to the frame.

Disclosed are cover systems for covering product such as grain. An example cover system includes a cover having at least one perforated tunnel extending across at least a portion of the cover (e.g., with an end to or beyond an edge of the cover). The perforated tunnel can include a bottom membrane with perforations, a cap strip membrane attached to the top side of the bottom membrane, and an air permeable filler material between the bottom membrane and the cap strip membrane. The perforated tunnel can have an air inlet at its end for drawing in air to hold down the cover by suction.

The water draining and collection system for monocoque vehicles applied with tonneau cover or similar object of present invention is aimed to solve the drawbacks described in the prior art through a water collection system for monocoque vehicles applied with tonneau cover or similar comprising a set of rails (10) and (20) of specific shape positioned on bed side and front faces between the plastic finishes (101) and (102) e bedliners (100) avoiding water intake and improving the draining system. This new embodiment applied in the water collection system allows an easy deployment and application in any bed monocoque vehicle model, efficiently solving the problem of water intake and assuring a better water draining.
